The Sulfur–Iodine (S–I) cycle has been considered as one of the efficient and promising thermochemical water-splitting cycles for hydrogen production using nuclear energy. However, the catalytic SO3 decomposition process in the S–I cycle demands high temperature heat (800°C). Existing...

Cracking of heavy naphtha is studied experimentally in a nanosecond pulsed DBD plasma reactor. The system has been evaluated for instant production of light gaseous hydrocarbons in the range of C1–C3 and hydrogen via continuous hydrocarbons cracking at room temperature and atmospheric...

This study utilizes the SIMPLE-C algorithm and Arrhenius form of reaction model to simulate the three-dimensional laminar flow field and the reaction in a cylindrical methanol reformer under steam reforming. Then the effect of geometrical and thermo-fluid parameters on the heat and mass...

Brewery wastewater was converted H2 by anaerobic sludge in batch experiments. A three-factor three-level experimental design of Box-Behnken method was adopted to find the optimum H2 production conditions. The effects of three major influence factors, temperature, pH and brewery wastewater...

Experiments were conducted in an Anaerobic Batch Reactor (ABR) to assess the influence of pH, organic load and retention time on hydrogen production using pig manure as substrate. The study was conducted in two stages: the first stage focused on the effect of pH and the second stage assessed the...

To address the problem of fossil fuel usage at the Missouri University of Science and Technology campus, using of alternative fuels and renewable energy sources can lower energy consumption and hydrogen use. Biogas, produced by anaerobic digestion of wastewater, organic waste, agricultural...

The effect of substrate concentration on continuous H2 production from a sucrose-rich synthetic wastewater was investigated in this work. The maximum H2 production rate of 2.89 m3 H2/m3/d achieved at 7000 mg COD/L while the peak ethanol concentration of 2840 mg/L was observed at 5000 mg...

Cellulose, a major component of woody biomass, was gasified to hydrogen rich gas using a reduced nickel catalyst in hot-compressed water of around 350 °C and 18 MPa. During the gasification, steam reforming and methanation can occur, and the methanation was prevented at subcritical condition....

A detailed comparative study on thermodynamic and experimental analyses of glycerol reforming for hydrogen production has been conducted in terms of the effects of temperature, pressure, water to glycerol feed ratio, feeding reactants to inert gas ratio and feeding gas flow rate (residence...

One of the main disadvantages of the dark fermentation process is the cost associated with the stages needed for obtaining H2 producing microorganisms. Using anaerobic microflora in fermentation systems directly is an alternative which is gaining special interest when considering the...
